Flexural (Moment) Capacity of Ultra-high Performance Fiber Reinforced Concrete Beams
Bibliographic record
Abstract
Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is a relatively new generation of cementitious material exhibiting exceptional mechanical characteristics. One of the main applications of this new material is strengthening existing bridges and the construction of new Igirders during the rehabilitation process. Previous research on (UHPFRC) beam girders and prestressed girders found the analytical moment capacity to be 76% of the experimental (test) results. A method based on strain compatibility, equilibrium and the stress-strain relationships is developed to determine the flexural capacity of UHPFRC beams with about 90% accuracy between experimental and numerical capacities. A testing program of five beam specimens is conducted at Ryerson University Structural Laboratory to verify the experimental results. Furthermore, the results of the finite element numerical simulation of ABAQUS software using concrete damage plasticity (CDP) constitutive model predict the flexural capacity of the tested UHPFRC beams reasonably well.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
